MEXICO CITY, May 9, 2025 – Harbour Energy has successfully appraised its Kan discovery in Block 30 offshore Mexico, increasing its estimate to 500 million barrels of oil-in-place, the company said on Thursday.

The appraisal campaign in the Salina del Istmo Basin concluded on time and within budget, validating higher-than-expected volumes. Harbour now estimates gross recoverable resources at approximately 150 million barrels, marking a 50% rise over previous projections.

“It validates the quality of the Kan discovery and demonstrates our ability to safely and efficiently deliver high-value resource growth,” Block 30 exploration and appraisal manager Sergio Calles added. “The results open a clear path towards potential development.”

Harbour said it will continue engaging with Mexican authorities and stakeholders to ensure the development aligns with national priorities, supports local content and upholds environmental stewardship.
